spi-imx: Implements handling of the SPI_READY mode flag.

2017-04-25T15:37:53Z

This patch implements consideration of the SPI_READY mode flag as defined in spi.h. It extends the device tree bindings to support the values defined by the reference manual for the DRCTL field. Thus supporting edge-triggered and level-triggered bursts. Signed-off-by: Leif Middelschulte Signed-off-by: Mark Brown

spi: pl022: Document property values

2017-03-20T11:24:25Z

The property "pl022,com-mode" can only assume one of the values of the enum ssp_mode, defined in include/linux/amba/pl022.h List the possible numeric values and report the associated meaning. Signed-off-by: Antonio Borneo Signed-off-by: Mark Brown

spi: pl022: remove nonexistent properties from DT binding example

2017-03-20T11:23:31Z

The properties "pl022,hierarchy" and "pl022,slave-tx-disable" were initially proposed till patch V4 [1] but then discarded in V5 [2] when the patch set was taken over by another developer, as explained in patch history in [3]. The above properties never landed in mainline code but were then listed in the binding example by a following commit dc715452e914 ("spi: pl022: use generic DMA slave configuration if possible") and later on they were copy-paste in some board's DT. Remove the nonexistent properties from the example. Also remove a spaces-only line at the end of the file.

spi: lantiq-ssc: add support for Lantiq SSC SPI controller

2017-02-14T17:10:40Z

This driver supports the Lantiq SSC SPI controller in master mode. This controller is found on Intel (former Lantiq) SoCs like the Danube, Falcon, xRX200, xRX300. The hardware uses two hardware FIFOs one for received and one for transferred bytes. When the driver writes data into the transmit FIFO the complete word is taken from the FIFO into a shift register. The data from this shift register is then written to the wire. This driver uses the interrupts signaling the status of the FIFOs and not the shift register. It is also possible to use the interrupts for the shift register, but they will send a signal after every word. When using the interrupts for the shift register we get a signal when the last word is written into the shift register and not when it is written to the wire. After all FIFOs are empty the driver busy waits till the hardware is not busy any more and returns the transfer status.
